Swimming Wank

My mate and I (15 also but less developed) were swimming once and there was no one else in the pool. We both had obvious boners. We would go to the bottom of the pool, pull down our shorts and wank and then come up to the surface. After a while when I was down wanking he came down too and pulled down his pants revealing his thick cock with blonde pubes. He swam over and grabbed hold of my cock and rubbed. We both went up for air next to each other, our boners touching. We went down again and he sat on my legs and rubbed my boner furiously. A white cloud of cum came out. After more air we came down again and I wanked him making him cum clouds everywhere. We got more air and just floated next to each other our two cocks touching each other. We swam some more and got out and wanked together in the changing room again.
